In this work, Ru Pd alloy nanoparticles were uniformly decorated on a two-dimensional reduced graphene oxide (rGO) sheet by an chemical co-reduction process. The resulting products were characterized by various physiochemical techniques such as X-ray diffraction, Raman spectroscopy, energy-dispersive X-ray spectroscopy, inductively coupled plasma atomic absorption spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. Further, the synthesized Ru Pd @rGO nanocomposites have been employed as a heterogeneous catalyst for three different catalytic reactions: (1) dehydrogenation of aqueous ammonia borane (AB); (2) hydrogenation of aromatic nitro compounds using ammonia borane as the hydrogen source, and (3) for the synthesis of aromatic azo derivatives. The present work illustrates the sustainable anchoring of metal nanoparticles over the surface of rGO nanosheets, which could be used for multifarious catalytic reactions.
在本工作中，通过化学共还原法将钌钯合金纳米颗粒均匀地修饰在二维还原氧化石墨烯（rGO）片上。通过多种物理化学技术对所得产物进行了表征，如X射线衍射、拉曼光谱、能量色散X射线光谱、电感耦合等离子体原子吸收光谱、X射线光电子能谱和透射电子显微镜。此外，合成的RuPd@rGO纳米复合材料已被用作三种不同催化反应的多相催化剂：（1）氨硼烷（AB）水溶液的脱氢反应；（2）以氨硼烷为氢源对芳香族硝基化合物进行氢化反应；（3）用于合成芳香族偶氮衍生物。本工作展示了金属纳米颗粒在rGO纳米片表面的可持续锚定，可用于多种催化反应。
